communications components key features ? low insertion loss high power handling proven reliability 9xx, 14xx and 15xx variants the jdsu fused coupler, pm combiner e nables the efficient combination of two orthogonally polarized sources of light at the same wavelength such that they are output through the same, single fiber output. in optical amplifiers this provides a doubling of pump power whilst ensuring pump redundancy should a pump failure occur. applications include high power optical amplifiers and undersea systems. all ports consist of polarization maintaining fiber. applications ? erbium doped fiber amplifiers (edfas) raman amplifiers coherent optical communications fused coupler, pm combiner north america : 800 498-jdsu (5378) website : www.jdsu.com worldwide : +800 5378-jdsu
